It is a prokaryotic cell: they do not have a nucleus, they have a lack of membrane bound organelles and they do not form spindle fibres during division.

What organelles are present in bacteria?
Cell wall, capsule, flagellum. mesosome, cell membrane, ribosomes and pillus.
2 of 9
Describe the structure of the cell wall (within bacteria)
It does not contain cellulose, it is made of peptidogylcan (a polysaccharide cross linked by peptide chains).
3 of 9
What is a capsule?
A protective layer of mucus layer which prevents dehydration; it also allows bacteria to form colonies.
4 of 9
What is a flagellum?
It is a tail like structure used for cell movement.
5 of 9
What is a mesosome?
It is an infolding of the cell surface membrane.
6 of 9
What are ribsomes?
They are the site at which protein synthesis occurs (they are free within the cytoplasm).
7 of 9
What are pilli?
They are protein tubes that allow bacteria to attach to surfaces and are involved in cell to cell attachment.
8 of 9
Describe the structure of viruses.
They a small organic particles that consist of a strand of nucleic acid (can be RNA or DNA) and they consist of a protein coat.
